Working Principles

Working Principles

Figure 2-7 shows the conceptual diagram. AC power enters rectifiers through the AC power distribution unit (PDU). The rectifiers convert the AC power input into -48 V DC power output, which is directed by the DC PDU to DC loads along different routes.

When the AC power is normal, rectifiers power DC loads and charge batteries. When the AC power is absent, rectifiers stop working and batteries start to power loads. After the AC power resumes, rectifiers power DC loads and charge batteries again.

The SMU monitors the operating status of each component in the power system in real time and performs appropriate intelligent control. When detecting a fault, the SMU generates an alarm. The SMU monitors and regulates the temperature control unit based on the temperature measured by the temperature sensor to ensure the normal operating temperature for the cabinet.
